V COMBINED WINDOW VENTILATOR AND SHADE.

SPECIFICATION forming part of Letters Patent No. 367,195, dated July 26,1887.

Application filed April 20,4887. Serial No. 235,480. (No model.)

' description.

The object of my invention is to provide a new and improved windowventilator and' shade, which permit of ventilating the room withoutcausing draft, and at the same tim serve as a window-shade.

The invention consists in the construction and arrangement of. variousparts and details and combinations of the same, as will be fullydescribed hereinafter, and then pointed out in the claims.

Referenceis to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation, partly broken away and in section, ofmyimprovement. Fig. 2 is a side elevation of the same in a closed orfolded position. Fig. 3 is asimilar view ofthc same in an open position.Fig. 4-is a vertical section of the same on the line a: w of Fig. 1,showing the window open.

To the'sides A of the window-casing and directly above the window-sill Bare seen red the strips 0, to the lower ends of which are hinged theends of an inverted-U-shaped frame, D, extending upward and being ofabout the same height as the window'casing. The side arms of the frame Dare each connected with the strips 0 by the folding canvas strips E, andthe frame D can be held in a vertical closed position, as shown in Figs.1 and 2, by the hooks F, pivoted to the sides of the window-casing andengaging with their hook ends the pins G,secured to the sides of the Ushaped frame D. The latter is held in an inclined position, as shown inFigs. 3 and 4., by the arms H, pivotally connected with each other attheir inner ends and pivoted at their outer ends to the sides of theframe D and the sides A of the window-casing, respectively.

On the upper end of the U-shaped frame D,

and in front of the same,is mounted in suitable bearings on said frame Dthe spring shaderoller I ,of any approved construction,and cartheU-shaped frame D. The outer guide, L

rying the shade J,provided near its lower end with sidewise-extendingguide-plates K, held between and adapted to slide in guides L andL,formed on the inner edges of each side of 5 terminates a shortdistance below the shade roller I and bends outward to admit the guideplate'K, as illustrated in Fig. 4. The shaderoller I may be covered upby an ornamental front plate, N, secured to the frame D,so as to hidethe roller and its bearings. Now,it will be seen that the shade J can bepulled down or let up fully or only partly in the closed or openedposition of the frame D, thus serving as a shade in the usual manner forthe windows 0, admitting or preventing the passage of the rays of light,as desired. 4

When'it is desirable to ventilate the room without causing a draft, thenthe frame D is placed in an inclined position, as shown in Figs. 3 and4, by unhooking the hooks F from the pins Gand then moving the frame Doutward from the window-casing until the folded armsH are extended, asshown in Fig. 3. The sashes of the windows 0 are then opened and theshade J is pulled down so that the frame D, the shade J, and the canvasstrips E form a-casing in front of the window, which casing is closed infront, at the bottom, and on the sides, and is opened at the top,'sothat the fresh air entering through the open sashes has to pass upwardin order to enter the room, thus preventing draft.

The canvas strips E may be directly attached to the sides A ofthewindow-casing instead of to the strips 0, which may be entirelydispensed with.v

' Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a window ventilator and shade, the combination, with a U-shapedframe pivoted to the lower ends of the window-casing,ofa window-shadesecured to a roller hung on the said U-shaped frame, substantially asdescribed.

2. In a window ventilator and shade, the combination, with a U-shapedframe pivoted to the'lower end of the window-casing, of fold ing stripssecured to the sides of the casing 2 semgs dow-shade secured to a rollermounted on the said U shaped frame, substantially as described.

3. In a window ventilator and shade, the combination, with a U-shapedframe pivoted to the lower end of the window-casing, of folding stripssecured to the sides of the casing and to the sides of the said frame,means, substantially as described, for holding said frame in an inclinedopened position, and a window shade secured to a roller mounted on thesaid U shaped frame, substantially as described.

i. In a window ventilator and shade, the combination,with an inverted- Ushaped frame pivoted at its ends to the lower ends of the sides of thewindoweasing, of folding strips secured to the sides of the casing andto the sides of said frame, a shade-roller held on the upper end ofsaidframe, and a shade mounted on said roller and adapted to be moved on theU-shaped frame, substantially as shown and described.

5. In a window ventilator and shade, the combination, with an inverted-U-shaped frame pivoted at its ends to the lower ends of the sides of thewindow-casing, of folding strips connecting the sides of said frame withthe sides of the window-casing, a shade-roller held on the upper end ofsaid frame, a shade mounted on said roller, and guide-plates sccured tothe lower end of said shade and adapted to slide in guides formed onsaid U- shaped frame, substantially as shown and dc scribed.
